Application filed September 8, 1920. serial No. 408,087.

To all whom it may concern:

Be it known that l, HERMANN Surro- HAUSSEN, residing 'at 23, Bredene erstr., Essen, Germany, a citizen oi the crman Republic, have invented a certain new and useful Improvement in Ball-Bearings, for which I" have filed an application-in Germany on November l, 1915, of which the following is a specification. d f

. This invention refers to a ball bearing especiaily intended for rapidly rotating sha its which in addition to a simple and reliable construction also permits of both an axial movement and also an oblique setting of the shaft within certain limits.

The invention will be described with reference to the accompanying drawing, which shows a longitudinal section through the ball bearing together with the adjacent parts concerned.

A denotes a vertical shaft which rotates rapidly when running and is rigidly connected to the inner bearing ring A of the ball bearing. A portion of the peripheral surface of the bearing ring A is formed with a cylindrical surface a coaxial with the axis of rotation of the shaft A and so forming the inner bearing surface for a row of balls B. The corresponding bearing surface for the balls B is formed by a circular groove 0 which is cut in the cylindrical inner surface of an outerbearing ring 0 and the diameter of which circular groove of exceeds the diameter of the balls 18 in size.

The bearing ring A has on its lower end a collar a which fits over a hollow neck on the cylindrical surface a and together with the groove 0 prevents the balls from fallin down. The bearingring C, the peripheral surface of which has two conical surfaces 0 and c of corresponding pitch, and the bases of which are turned toward each other,

rests by means of these conical surfaces on two rows of balls D and D which in their turn are each supported against hollow neck e and e provided on the'inner wall of the two part outer bearing rin E audit. The

radius of the hollow nec e and e is greater than the diameter of the balls D and D and are of suchdimensions that the balls D and D can adjust themselves up Wardly o down ardly wi hin certa n hmita The above described ball bearing possesses the property that, when the shaft A rotates, the balls B can roll within certain limits in the direction of the longitudinal axis of the shaft A on the cylindrical surface a and furthermore an automatic adjustment of the balls D and D is possible upwardly or downwardly along the hollow necks e and c The result is, in addition to a simple and reliable construction of the ball bear- 1 ing, the important advantage that an axial movement or an oblique position of the shah: A cannot bring about any jamming in the ball bearing.

Without in any way altering the essential features of the invention, the bearing ring C may also be mounted to rotate on the other bearing ring E E by means of a single ring 0:" balls, provided the support of this ring of balls is of such a nature that it permits otthe shaft being set obliquely.

Claims.

1. In a ball bearing, the combination with an inner member having an external hearing surface and an outer member havin an internal bearing surface, of an intermediate ring having internal and emernai bearing surfaces coactingiwith the first mentioned bearing surfaces respectively, and balls interposed between each pair of coacting hear ing surfaces, one of said bearing surfaces being cylindrical to permit relative axial movement of the inner and outer members, and another of sold bearlng surfaces being longitudinally curved topermit relative angular movement of said members.

" 2. A ball bearing according to claim 1 in and the outer member has a pair of longitudinally curved bearing surfaces coacting respectivel with the external bearing surfaces ont e intermediate ring, a sense of balls being interposed between each pair of coacting'bearing surfaces.
